Patent number: 9205829Abstract: A method for operating a traction vehicle, especially a locomotive, wherein the power delivered by a drive system is produced by at least two internal combustion engines, each of which is functionally connected to a generator for producing electric power, the engines preferably being gas engines, even more preferably lean gas engines. A previously determined number of separate power stages ranging from a minimum power up to a nominal power of the drive system is provided. The interval between all directly adjacent power stages is selected so that it corresponds to a constant fraction of the nominal power of the drive system.Type: GrantFiled: December 9, 2013Date of Patent: December 8, 2015Assignee: MTU FRIEDRICHSHAFEN GMBHInventor: Joachim Hug

Patent number: 8810907Abstract: A microscopy system and method allow observing a fluorescent substance accumulated in a tissue. The tissue can be observed at a same time both with visible light and with fluorescent light. It is possible to observe a series of previously recorded fluorescent light images in superposition with the visible light images. An end of the series of images may be automatically determined. A thermal protective filter may be inserted into a beam path of an illuminating system at such automatically determined end of the series. Further, the fluorescent light image may be analyzed for identifying a coherent fluorescent portion thereof. A representation of a periphery line of the coherent portion may be generated, and depths profile data may be obtained only from the coherent portion. An illuminating light beam for exciting the fluorescence may be modulated for improving a contrast of fluorescent images.Type: GrantFiled: July 29, 2011Date of Patent: August 19, 2014Assignee: Carl Zeiss Meditec AGInventors: Michael Haisch, Christoph Hauger, Hartmut Wolf, Joachim Hug, Schwarz Brigitta, Gerhard Gaida, Andreas Raabe
